Physogaleus secundus is a small species pretty common for the Eocene across the globe. I think this could be it. I believe it is distinguished from species of Galeorhinus by having a lack of a labial bulge at the base of the crown. In other words, if you turn that tooth around and look at the base of the crown and do NOT see an enamel bulge/overhang, then I would say it’s Physogaleus secundus.
